commit 7a1c717c8bba1d046c37c75c3d8c110aeba3cc09
Author: Pekka Seppänen <pexu@sourceware.mail.kapsi.fi>
Date:   Wed Aug 30 12:16:32 2023 +0300

    Reentrancy, conditionally provide default __getreent() implementation
    
    Conditionally provide default __getreent() implementation only if
    _REENT_THREAD_LOCAL is not defined.  If struct _reent is replaced by
    dedicated thread-local objects neither the structure nor _impure_ptr is
    available.
